1 x 10-3 make sure the -3 is above the 10.
First row, the answer on the left , -5 3/4 - 4 2/3
Answer:
15x
Step-by-step explanation:
because i multiply i side by side and copy the variable
First we have to assume that each quarter touched each other. Hence the area of the table not covered by the coins (A) is equal to the total area of the table (At) minus the total area of the coins (Ac). Coins are circle, so

and r =24.26mm. The area of one coin is then 1848.98mm^2. Hence the equation is A = At - xAc where x is the number of coins.
